A plurality of pores are configured to vacate a distinct ratio of the area of the walls.

The walls defining the above-mentioned chambers are adjacent to the surface of the internal Wallis of the hollow distributor, collector and deflector bodies.

The wall surfaces of the pores in at least a part of the wall body (11) exhibit hydrophilicity.

For that purpose, the wall surfaces (6, 7) that delimit the space (13, 12) adjacent to the wheel are designed in such a way that the flow next to the stationary wall surfaces (6, 7) may be influenced in order to reduce attrition.

The data receiving means can also be oriented opposite a wall surface of said housing.

An opening (23) is situated in a surface of the sides (13, 14, 15) delimiting the space (25).

The direction along which the object bearing base rotates in the heating portion is perpendicular to the rotation shaft around which the object bearing base rotates, so that foaming materials on external walls of each paper container can be heated.

The wall surfaces extend vertically over at least half the circumference of the device (1), creating a billboard surface.

A set consisting of two identical display cases (1) having side walls (2d) slightly extended in respect to the surface of back walls (2b).

The at least one stent member (22) has openings through wall surfaces of the stent to permit radial expansion.

The surface or parts of the surface that forms walls within the measuring cell or the cavity is/are coated with one or more different metal layers (M1, M2).

With the reduction in the interrogation field at the surface of the walls (6, 8) due to linings (25, 26) the eddy currents in those walls are greatly reduced.

Because the surface energy of the sidewalls is lower than that on the protrusions, polymer dewetting from the sidewalls is promoted, which makes the polymer film discontinuous along the edges of patterns.

Tile pieces (1, 7 and 8) used as a material for finishing inner and outer wall surfaces and floor surface of a building.

The treated area of the inner wall of the place concrete walls amounted to approximately 666 m2.
